Seating chair with a supporting frame

ABSTRACT

This invention relates to a supporting frame structure of a rest of a seating chair, wherein a nose and a dent which are formed by a connection part of a vertical part of the supporting frame correspond to a catch of a nose and a dent which are located on a edge of a end of a horizontal part, and by assembly and correspondingly coupling an elastic packing piece and a locating part, the vertical part of the supporting frame can freely be rotated and adjusted in the right or left, or clockwise or counterclockwise direction to make a user who sits on the seating chair with the supporting frame structure feel more comfortable, and, furthermore, to make the seating chair be fitted for any user to use.

FIELD OF THE INVENTION

[0001] The present invention relates to a supporting frame structure of a rest of a seating chair, and more particularly, to a supporting frame structure of a rest of a seating chair with freely rotating properties in the left or right, or clockwise or counterclockwise direction to make a rotating angle of the supporting frame structure be more suitable for practical demands of a user.

BACKGROUND OF THE INVENTION

[0002] In structures of normal seating chairs with rests, as shown in FIG. 4, the ordinary structure has a L-shaped supporting frame 1, a row of adjusting holes 111 are located inside the vertical part 11 to be assembled with the adjusting height device, which is not shown in the figure, of the rest, and several restraining position holes 121 are located inside the horizontal part 12 to make the supporting frame 1 assemble with the back of the seating chair. However, due to the reason that the ordinary rest of the seating chair is assembled with the supporting frame 1, the structure of the supporting frame 1 is in the fixed L-shaped so that the ordinary rest of the seating chair can only have the function of adjusting the height of the rest by setting the adjusting holes without the ability to adjust the rest in the horizontal direction. Thus, it is a problem for those users who would sit on the seating chair for a long time to make their elbows feel more comfortable without the ability to adjust the rest in the horizontal direction.

SUMMARY OF THE INVENTION

[0003] In view of above, the primary purpose of the present invention is to provide a supporting frame structure of a rest of a seating chair a supporting frame structure of a rest of a seating chair, wherein a nose and a dent which are formed by a connection part of a vertical part of the supporting frame correspond to a catch of a nose and a dent which are located on a edge of a end of a horizontal part, and by assembly and correspondingly coupling an elastic packing piece and a locating part, the vertical part of the supporting frame can freely be rotated and adjusted in the right or left, or clockwise or counterclockwise direction to make a user who sits on the seating chair with the supporting frame structure feel more comfortable, and furthermore, to make the seating chair be fitted for any user to use.

[0008]FIG. 4 is a structure view showing the structure of the supporting frame of the rest of the seating chair in accordance with the prior art.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Firstly, referring to FIG. 1, the structure of the supporting frame 6f the rest of the seating chair in accordance with the present invention, the supporting frame 2 is composed of the vertical part 21, the horizontal part 22, the elastic packing piece 23, and a locating part, wherein adjusting holes 211 are properly located inside a end of the vertical part 21, jointing segment 212 is extended along the other end of the vertical part 21 in the vertical direction of the vertical part 21, a open through pivot hole 213 is located inside a proper position of the end of the jointing segment 212, and nose 214 and dent 215 are separated by a certain spacing and located in the periphery, which is near the jointing segment 212, of the open through pivot hole 213.

[0010] The horizontal part 22 is in a pre-determined designed shape, wherein several restraining position holes 221 are located inside an end of the horizontal part 22, a open through pivot hole 222 is located in a proper position and inside the other end of the horizontal part 22, and several noses 223 and dents 224 are separated by a certain spacing and located in the periphery of the open through pivot hole 222.

[0011] While in assembling the seating chair, as shown in FIG. 2, the horizontal part 22 is above the position where the vertical part 21 couples with the jointing segment 212, and an elastic packing piece 23 is assembled above the open through pivot hole 222 of the horizontal part 221. By letting the restraining position holes 24 go through the elastic packing piece 23, the pivot hole 222, and 213, each of the noses 223 of the horizontal part 22 corresponds to the corresponding dent 215 of the vertical part 21, and the dents 224 correspond to the noses 214 to form a scarfing type for assembling the vertical part 21 with the horizontal part 22 to get the supporting frame 2 of the present invention.

[0012] While in using the supporting frame 2, as shown in FIG. 3, the user can freely rotate the supporting frame in the left or right direction, and rotate the vertical part 21, which corresponds to the restraining position part 24, of the supporting frame 2 to a proper angle to make the dent 215 and 224 scarf with the corresponding nose 223 and 214. During the rotation, the elastic packing piece 23 sticks with each dent 215, 224, noses 214, and 223, depending on the different situations, to form a proper elastic sticker for making the supporting frame of the rest of the seating chair rotate in different ranges of different angles to make the user feel more comfortable and fit demands of the user.

[0013] The present invention has been described hitherto with exemplary preferred embodiments. However, it is to be understood that the scope of the present invention need not be limited to the disclosed preferred embodiments. On the contrary, it is intended to cover various modifications and similar arrangements with the scope defined in the following appended claims. The scope of the claims should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements. 

What is claimed is:
 1. A supporting frame of a rest of a seating chair comprising: A vertical part, a horizontal part, elastic packing pieces, and restraining position part, wherein a row of adjusting holes and restraining holes are located inside a end of the vertical part and a end of the horizontal part.
 2. The supporting frame of claim 1 wherein adjusting holes are properly located inside a end of the vertical part, jointing segment is extended along the other end of the vertical part in the vertical direction of the vertical part, a open through pivot hole is located inside a proper position of the end of the jointing segment, nose and dent are separated by a certain spacing and located in the periphery, which is near the jointing segment, of the open through pivot hole, and the vertical part and the elastic packing piece are in the position above the jointing segment to let a restraining position part to locate and fix the elastic packing piece and the two pivot holes for freely rotating the supporting frame in the left or right direction.
